Abstract

An optical fiber (10) includes a rare-earth doped inner core (12) surrounded by an outer core (14), and a pump core (16) attached to the outer core (14). The pump core (16) is separated into branched regions each partially attached to the outer core (14). Excitation light, from an external pump source is coupled into each branched region (18) of the pump core (16), propagates into the outer core (14), without breaking open the outer core (14), and leaks into and is absorbed by the inner core (12). The rare-earth ions contained in the inner core (12) are capable of being stimulated by this received optical power, thereby providing the desired amplification of an optical signal propagating through the optical fiber (10).
